A Nonlinear Hybrid Life Support System: Dynamic Modeling, Control Design, and Safety Verification.

Journal article

We present control design for a variable configuration CO2 removal (VCCR) system, which exhibits a hybrid dynamical character due to the various modes in which one needs to operate the system. The VCCR is part of an overall NASA Air Recovery System of an intended human life support system for space exploration. The objective of the control system is to maintain CO2 and O2 concentrations in the crew cabin within safe bounds. We present a novel adaptation of the model predictive control techniq...
